I took this information out of a JSON and initialized it, but I don't understand how I can get the data out of the form to pass them to the cardView afterward. Or is there an easier way?
MainActivity
public class MainActivity extends AppCompatActivity {
Context context;
Example example;
Response responses;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RecyclerView rv = (RecyclerView)findViewById(R.id.cartView);
LinearLayoutManager llm = new LinearLayoutManager(context);
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("Secret Url") // For some reason I cannot show the url
.addConverterFactory(GsonConverterFactory.create())
.build();
Api api = retrofit.create(Api.class);
ArrayList arrayList = new ArrayList();
Call<Example> call = api.getRespon();
call.enqueue(new Callback<Example>() {
#Override
public void onResponse(Call<Example> call, Response<Example> response) {
if(response.code() != 200){
Toast.makeText(MainActivity.this, "Connect",Toast.LENGTH_SHORT).show();
return;
}
Example examples = response.body();
for(int i=0; i<examples.getResponse().size(); i++){
String f_name = response.body().getResponse().iterator().next().getfName();
String l_name = response.body().getResponse().iterator().next().getlName();
String birthday = response.body().getResponse().iterator().next().getBirthday();
String SpecName = response.body().getResponse().iterator().next().getSpecialty()
.iterator().next().getName();
int SpecId = response.body().getResponse().iterator().next().getSpecialty()
.iterator().next().getSpecialtyId();
}
}
#Override
public void onFailure(Call<Example> call, Throwable t) {
Toast.makeText(MainActivity.this, "Fail",Toast.LENGTH_SHORT).show();
}
});
}
}
At the moment I have not finished the class because I can not specify the data that have been implemented
PersonaAdapter
public class PersonAdapter extends RecyclerView.Adapter<PersonAdapter.PersonViewHolder> {

I solved the problem by creating a list and putting the data into an array
List<Worker> workerList = new ArrayList<>();
for(int i = 0; i < examples.getResponse().size(); i++){
String f_name = response.body().getResponse().get(i).getfName();
String l_name = response.body().getResponse().get(i).getlName();
String birthday = response.body().getResponse().get(i).getBirthday();
String SpecName = response.body().getResponse().get(i).getSpecialty()
.iterator().next().getName();
String SpecId = response.body().getResponse().iterator().next().getSpecialty()
.iterator().next().getSpecialtyId().toString();
String AvatarUrl = response.body().getResponse().get(i).getAvatrUrl();
workerList.add(new Worker(f_name, l_name, birthday, SpecName, SpecId, AvatarUrl));
In Worker has a constructor and getter
Watching a tutorial I have a listView.
I have an EditText and want to filter the listView content by what is in the EditText.
Here is my adapter class:
class ListViewAdapter extends BaseAdapter {
private List<listAudienceFriendsExcept> FriendsExceptList;
private Context context;
ListViewAdapter(Context context, List<listAudienceFriendsExcept> FriendsExceptList) {
this.context = context;
this.FriendsExceptList = FriendsExceptList;
}
#Override
public int getCount() {
return FriendsExceptList.size();
}
#Override
public Object getItem(int pos) {
return FriendsExceptList.get(pos);
}
#Override
public long getItemId(int pos) {
return pos;
}
#SuppressLint("ViewHolder")
#Override
public View getView(int position, View view, ViewGroup viewGroup) {
view = LayoutInflater.from(context).inflate(R.layout.model,viewGroup,false);
TextView name = view.findViewById(R.id.name);
ImageView avatar = view.findViewById(R.id.avatar);
final CheckBox checkbox = view.findViewById(R.id.checkbox);
final listAudienceFriendsExcept thisListAudienceFriendsExcept = FriendsExceptList.get(position);
// Setting data to listView items
checkbox.setTag(thisListAudienceFriendsExcept.getId());
name.setText(thisListAudienceFriendsExcept.getGetFirstName());
if (!thisListAudienceFriendsExcept.getGetAvatar().equals("default_avatar.png")) {
Glide.with(avatar)
.load(API_BASE_URL+"files/avatar_back_files/"+thisListAudienceFriendsExcept.getGetAvatar())
.circleCrop()
.fitCenter()
.into(avatar);
} else if (thisListAudienceFriendsExcept.getGetSex().equals("male")) {

.load(API_BASE_URL+"tools/img/female_default_avatar.png")
.circleCrop()
.fitCenter()

}
return view;
}
}
Here my list:
static class listAudienceFriendsExcept {
#SerializedName("id")
private int id;
#SerializedName("first_name")
private String first_name;
#SerializedName("last_name")
private String last_name;
#SerializedName("avatar")

Here my populateListView:

ListView listViewAudienceFriendsExcept = findViewById(R.id.listViewAudienceFriendsExcept);
ListViewAdapter adapter = new ListViewAdapter(this, thisList);
listViewAudienceFriendsExcept.setAdapter(adapter);
}
I tried that:
final TextInputEditText first_name_edit_text = findViewById(R.id.first_name_edit_text);
first_name_edit_text.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
public void onTextChanged(CharSequence cs, int s, int b, int c) {
friendListAdapter.getFilter().filter(newText); // What is **friendListAdapter** in my case ?
}
I'm using Retrofit tho get data from server when activity start:
private void callServer() {
/*Create handle for the RetrofitInstance interface*/
df myAPIService = RetrofitClientInstance.getRetrofitInstance().create(df.class);
Call<List<listAudienceFriendsExcept>> call = myAPIService.getListAudienceFriendsExcept();
call.enqueue(new Callback<List<listAudienceFriendsExcept>>() {
#SuppressWarnings("NullableProblems")
#Override
public void onResponse(Call<List<listAudienceFriendsExcept>> call, Response<List<listAudienceFriendsExcept>> response) {
populateListView(response.body());
}
#SuppressWarnings("NullableProblems")
#Override
public void onFailure(Call<List<listAudienceFriendsExcept>> call, Throwable throwable) {
Toast.makeText(MainActivity.this, throwable.getMessage()+"èèè", Toast.LENGTH_LONG).show();
}
});
}
I have googled and found that: friendListAdapter.getFilter().filter(newText); But I don't know to use in my case.
Any Solution?
My other question:
How could I pass the user ID to php server ?
Thanks.`
You can use streams to filter.
//add this imports on your class or activity
//import com.annimon.stream.Collectors;
//import com.annimon.stream.Stream;
//import com.annimon.stream.function.Predicate;
List<listAudienceFriendsExcept> original_list=new ArrayList<>();
List<listAudienceFriendsExcept> search_list=new ArrayList<>();
EditText serch_field;
void setup()
{
//original_list=whatever the source of the list is
//be sure to populate the original list before proceeding here
populateListView(original_list);
serch_field.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
search_list = Stream.of(original_list).filter(new Predicate<listAudienceFriendsExcept>() {
#Override
public boolean test(listAudienceFriendsExcept item) {
// return item.getGetFirstName().toUpperCase().contains(serch_field.getText().toString().toUpperCase())||item.getGetLastName().toUpperCase().contains(serch_field.getText().toString().toUpperCase());//if you want to filter multiple fields
return item.first_name.toUpperCase().contains(serch_field.getText().toString().toUpperCase());//to filter first name only
}
}).collect(com.annimon.stream.Collectors.<listAudienceFriendsExcept>toList());
populateListView(search_list);
}
#Override
public void afterTextChanged(Editable s) {
}
});
}
For the model
public class listAudienceFriendsExcept {
#SerializedName("id")
private int id;
#SerializedName("first_name")
public String first_name;
#SerializedName("last_name")
private String last_name;
#SerializedName("avatar")
private String avatar;
#SerializedName("sex")
private String sex;
public listAudienceFriendsExcept(int id, String first_name, String last_name, String avatar, String sex) {
this.id = id;
this.first_name = first_name;
this.last_name = last_name;
this.avatar = avatar;
this.sex = sex;
}
int getId() {
return id;
}
public String getGetFirstName() {
return first_name;
}
public String getGetLastName() {
return last_name;
}
public String getGetAvatar() {
return avatar;
}
public String getGetSex() {
return sex;
}
}
And on Gradle-dependencies add

Excuse my ignorance but I am very new to Android Studio and Java. I have adapted a lot the following code from another course to my needs, but it is not working.
I am trying to add custom markers to my Google maps Android app. Lhe locations of the markers are stored as geopoints on firebase. I have attempted to do so using cluster marker. The app crashes immediately when I attempt to run it with the following shortened error.
java.lang.NullPointerException: Attempt to invoke virtual method 'com.google.firebase.firestore.CollectionReference com.google.firebase.firestore.FirebaseFirestore.collection(java.lang.String)' on a null object reference

To solve this, please add the following line of code:
FirebaseFirestore mDb = FirebaseFirestore.getInstance();
Right before this line:
CollectionReference locationsRef = mDb.collection("Stop Locations");
So your FirebaseFirestore object is initialized correctly.
I am trying to pass this class as a parcelable in android.
public class Outfit implements Parcelable {
private List<Item> itemList;
private String mName;
private String mImageUrl;
public Outfit() {}
public Outfit(String mName, String mImageUrl) {
this.mName = mName;
this.mImageUrl = mImageUrl;
}
protected Outfit(Parcel in) {
itemList = in.createTypedArrayList(Item.CREATOR);
mName = in.readString();
mImageUrl = in.readString();
}
public static final Creator<Outfit> CREATOR = new Creator<Outfit>() {
#Override
public Outfit createFromParcel(Parcel in) {
return new Outfit(in);
}
#Override
public Outfit[] newArray(int size) {

}
};
public String getmName() {
return mName;
}
public String getmImageUrl() {
return mImageUrl;
}
#Override
public String toString() {
return mName;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel parcel, int i) {
parcel.writeTypedList(itemList);
parcel.writeString(mName);
parcel.writeString(mImageUrl);
}
}
the problem is that Item is abstract and itemList = in.creatTypedArrayList(Item.CREATOR) because Item does not have a CREATOR . Only its subclasses have this implementation.
Item.java
public abstract class Item implements Parcelable {
private String mName;
private String mColor;

dest.writeString(mColor);
dest.writeString(mImageUrl);
dest.writeTypedList(tags);

}
#Override

public void setmColor(String mColor) {
this.mColor = mColor;
}
public String getmName() {
return mName;
}
public void setTags(List<TagHolder> tags) {
this.tags = tags;
}
#Exclude // dont need this in our firebase database

I am able to parce a List as a parcelable array when I call put extra. But when I try to do so for outfit it gives error . Is there any way to pass Outfit as a parcelable?
Do you try using another method for the list?
#Override

parcel.writeList(itemList);
parcel.writeString(mName);
parcel.writeString(mImageUrl);
}
protected Outfit(Parcel in) {
in.readList(itemList, Item.class.getClassLoader());
mName = in.readString();
mImageUrl = in.readString();

TextView email = (TextView) view.findViewById(R.id.textEmailList);
//email.setText(Email[position]);
TextView gender = (TextView) view.findViewById(R.id.textGenderList);
//gender.setText(Gender[position]);

if (Name != null) {
Name.setText(UserInformation.getName());
}
if (email != null) {
email.setText(UserInformation.getEmail());
}
if (gender != null) {
gender.setText(UserInformation.getGender());
}
if (birthday != null) {
birthday.setText(UserInformation.getBirthday());
}
}
return view;
}
}
For setting values why are you using Class (UserInformation) instead of Class name use its object userInformation.
if (Name != null) {
Name.setText(userInformation.getName());
}
if (email != null) {
email.setText(userInformation.getEmail());
}
if (gender != null) {
gender.setText(userInformation.getGender());
}
if (birthday != null) {
birthday.setText(userInformation.getBirthday());
}
One more thing , make below values non-static
public class UserInformation {
private String Name;
private String Gender;
private String Email;
private String Birthday;
public UserInformation(String Name,String Gender,String Email,String Birthday){
this.Birthday=Birthday;
this.Email=Email;
this.Gender=Gender;
this.Name=Name;
}
public String getName(){return Name;}
public String getEmail(){return Email;}
public String getGender(){return Gender;}
public String getBirthday(){return Birthday;}
}
